SHEATH FOR BOOK COVERS.

SPECIFICATION forming part of Letters Patent No. 390,449, dated October 2, 1888.

Application filed May '7, 1887. Serial No. 237,437.

To all whom it may concern:

Be it known that 1, CHARLES H. GARYL, a citizen of the United States, residing at Kalamazoo,eounty of Kalamazoo, State of Michigan, have invented a new and useful Sheath for Book-Govers, of which the following is a specification.

This inventionhas for its object certain improvements hereinafter described and claimed, having reference to sheaths for covering temporarily the covers of books. Such sheaths are commonly made of heavy paper, the old way being to wrap a piece of paper over the book-cover and fold the sides and ends of the paper over the edges of the bookcovers and fasten them by sewing or gluing. More recent plans have been to make the sheaths of different pieces of paper adapted to be adjusted to fit book-covers of varying sizes, the sheaths being manufactured and supplied in quantities to the book-dealers. To sheaths of the latter construction this invention rcfers, my design being by my improvements to simplify them and add to their utility and appearance.

In the drawings forming a part of this specification, Figure 1 shows a perspective view of a book with a sheath nearly adjusted. Fig. 2 is a perspective view of a closed book,showing the sheath as it appears on the cover. Fig. 3 is a plan of one'half of the sheath before folding, and Fig. 4 is a plan of both parts of the sheath as they appear when ready for the trade.

Referring to the drawings and the letters marked thereon, a a show the two parts of which the sheath is composed. One end of these parts has a pocket to receive one of the covers of the book B, as in Fig. 4, by folding the end e on line 2 and then folding over the lap c and sticking it down. The edges 0 and c" are gumnied ready to moisten and stick to the parts on which they are lapped.

Between the lines 3 3 the back of the book is placed, the corners of one of the book-covers having been first inserted in the pockets 6 e. In adjusting the sheath to the book the right-hand part is first put on. The end a is then folded over the opposite cover, as in (N0 model.)

Fig. 1, the portion from s to the end of the sheath being folded in between the sheath and the book, Fig. 1, and the end a (with the size of book shown) is folded over on the inside of the book-cover on line 1, Fig. 4, as at a, at right side of Fig. 1. c is then folded down and stuck on part a. (See left of Fig. 1.) The V lines at s and the line at show the creases made in the paper by folding in this manner. This makes a strong handsomely'finished corner. It is the design to fold the pockets at the other ends in like manner; but, if preferred, the end c may be narrowed beyond the lid 0, as in Fig. 3, at left side. The end a is lapped or folded over a distance corresponding with the size of the book-cover in a given instance.

Referring to Fig. 4, the smaller the bookeover the nearer to the pocket 6 will the back of the book be placed and the farther the edge 0 will lap over on the edge of the other half of the sheath. The other half of the sheath, the left-hand half in Figs. 1 and 4 and the upper half in Fig. 2, the edge e having been first moistened to wet the gum, is placed on the book in the manner above de' scribed for adjusting the first half, with the additional action of sticking down the overlapping edge c".

It will be observed that the only engagement or connection of one part of the sheath with the other is the central lap, which is transversely to the book-covers. By this means the book has a more finished appear ance,and in closing the book the strain brought to bear on the sheath does not separate these partially-dried overlapping edges, as in prior constructions; but, on the other hand, as the strain comes lengthwise of the lapped edges it tends to hold them straight and firm until they dry. Thus there is no need to wait till the edges have dried before closing the book, as heretofore.

Having thus described myinvention, whatl claim as new, and desire to secure by Letters Patent of the United States, is

'A two-part sheath for a book cover, each part being constructed with a pocket in one end to receive and sheathe a corner of one The lap I of the covers, the other ends of the parts being adapted to fold over and sheathe the corners of the other cover in adjusting said parts to the cover, one part overlapping and ad- 5 hering to the other part centrally and transversely to the book -covers, substantially as set forth.

In testimony of the foregoing I have here unto subscribed my name in presence of two Witnesses.
